DEVICE FOR SECURING CHIMNEYS TO LAMP-BURNERS.

SPECIFICATION formingpart of Letters fPatent No. 436,069, dated September 9, 1890.

Application filed March 1, 1890.

To all whom, it may concern:

Be it known that I, JOSEPH MEADWAY, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Devices for Securing Chimneys to Lamp-Burners, of which the following is a specification.

The object of my invention is to produce a simple and efficient means for securing a lamp-chimney to a burner so that it cannot be accidentally removed or thrown oif; and its construction and operation will be fully andclearlyhereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 represents a side'elevation of a lamp, lamp-burner, and chimney, showing my improved device attached to the chimney and to the burner for holding the same firmly in place. Fig. 2 is a top view of the chimney-holder detached from the burner, showing it open, so that a chimney may be put in and fastened and the device secured to a burner at the same time. Fig. 3 is also a top planview showing a horizontal section through a chimney in orabout line ab, Fig. 1, and the chimney-holder securely fastened to it.

In said drawings, 1 represents an ordinary lamp, 2 the burner, and 3 the chimney.

The fastening device consists of a removable open ring 4, made preferably of springbrass, but any other suitable material may be used.

The top edge of the ring maybe ornamented, substantially as shown at 5, Fig. 1, or the top may be left plain, as shown in Figs. 2 and 3.

The open ends are each provided with a forwardly-projecting portion 6 and 6. The portion 6 is provided with a hole sufliciently large to allow the screw 7 to slip easily back and forth therein, and the portion 6 is provided with a screw-threaded hole adapted to Seria1No.342,258. (N0 model.)

engage with the screw-thread 0n the screw '7, so that by turning the screw by means of the thumb-piece 8 the space within thering may be either enlarged or contracted, according to the direction in which the screw is turned.

At the bottom of the ring 4, on its periphery, is a series of hook-shaped pieces 9 for fastening the device to a burner. In Fig. 1 I have shown these hook portions 9 so located as to require four, but three may be used, as shown in Figs. 2 and 3, or more or less than the number shown.

In using this deviceitis placed on a burner so that the hook portions will catch over the top edge 10 of aburner. (See Fig.1.) Then the chimney is inserted and the screw 7 is turned so as to draw the ring close and tightly to the chimney, substantially as shown in Fig. 3. At the same time the chimney is tightened in place the hook portions 9 are drawn over the top edge of the burner, as shown in Fig. 1, so that the chimney is held rigidly to the holding device and the holding device is simultaneously secured rigidly to the burner. There is no danger of the heat causing the glass to break within the ring, because the brass ring also takes the heat and expands substantially with the glass of which the chimney is composed.

I claim as my invention the following:

A lamp-chimney holder consisting of a re-' movable open spring-1 in g 4, provided with forwardly-projecting portions at the open ends, and a screw for drawing them together for rigid attachment to a chimney, in combination witha series of rigid hooks curving outward and inward from the lower edge of the ring for simultaneous rigid attachment to a lamp-burner, substantially as described.
